Well both of them are basically just ubuntu with other DE + some different shipped apps (they are "official" flavors). But sure, I bet regular Ubuntu would have managed an upgrade better. I've used vanilla Ubuntu pre-unity and during unity. Haven't tried it since the gnome 3 switch though.

The reason I went with Ubuntu Studio is just because I use this computer for music recording. Ubuntu Studio uses xfce though, which I don't like very much. I was happy therefore when I realized you could just apt-get the audio production meta package from ubuntu studio. Budgie seemed like a nice DE, so I wanted to try that one out.

To use this you need to list what you have, you need at least 2 Providers. One is the Source output and the other is the Sink. In this case I run modesetting (via Intel GPU) then use the AMD for when I need to run Steam and other stuff using:

Have you tried any of the DRI_PRIME stuff yet? The idea is that you use the default (built-in) GPU for your graphics then only use your eGPU for games.

Oh right, no, I haven't. I just wanted to get the thing to run every time I start my computer and not every 15 times. Because yesterday night, the GPU started up once when I booted. For some reason it only seems to work when I unplug the HDMI cable before booting. But I'll try it out! Thanks.

However upon reboot, it went automatically to wayland (possibly because it was installed?), and I had to click on the gear icon next to my login to set it back to Gnome on Xorg. But that doesn't matter for you and your eGPU stuff.

My information could be outdated, but my understanding was that Ubuntu Studio rolled a new kernel, which is a prime culprit for driver issues. A lot of the Ubuntu knockoffs, like Mint and I am guessing Budgie, do weird stuff like that, so if you really want to test driver support you should try vanilla. Doesn't mean you have to stick with it, but you can at least isolate the problem.
